A cofiguration that I sucesfully compiled and run using Gentoo-sources was used to compile a Vanilla kernel. I used make menuconfig to resave the configuration file and ensure compatibility. All other settings remained unchanged. Upon booting with the new kernel, there is obvious harware incompatibilities with the screen. Unfortunately little can be read because of this, but what can be seen is that the framebuffer uses an incompatible 800*600 screenmode other than the 1024*768 that has been requested through the vga=791 kernel option. Reproducible: Always Steps to Reproduce: 1. Use the config file I will attach to configure the vanilla sources. 2. Enable support for SiS under Character Devices > AGP support > DRI > SiS 3. compile and install 4. Reboot Actual Results: The screen fails to refresh, colors bleed into each other. Expected Results: Booted normally like the Gentoo kernel does using the same settings. hardware info: ECS Desknote A907 with the Transmeta Crusoe Processor ( ~500Mhz ) ( www.desknote.com.tw ) 00:00.0 Host bridge: Transmeta Corporation LongRun Northbridge (rev 01) 00:00.1 RAM memory: Transmeta Corporation SDRAM controller 00:00.2 RAM memory: Transmeta Corporation BIOS scratchpad 00:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Naturally this bug refers to kernels 2.4.19-gentoo-r10 and 2.4.20
umm, if this really is a kernel bug and it's off of vanilla sources, then theres nothing we can do about it ...
yep, if we fixed it, it would no longer be "vanilla" :)
